Scrolls

I have been playing for a while now and still dont realy know how to use/equip the scrolls, I have reams and reams of them, how do I use them ?When I "scroll" down them there isn't a button to use any of them, I have tried the hotkeys but to no avail ? I know I am oing something wrong but dont know what it is ??

If you have a magic scroll, you click on it, and press the "cast" button (Whatever it is for your platform). For PS3 it is R2.The scrolls only work once though, but you don't need to be a skilled mage to use them.
